pre amp

Hi all. I have an oddball problem I was hoping someone may be able to help with. I have a Harmon Kardon Citation 11 Pre-amp. It has been working fine but earlier today I turned it on and one of the meters on my Amp pegged. So I turned it off and checked the cables. Turned it on again and...

Hello, anyone tried to pair a Nad 3020 with Nad 214? I would like to get a bit more punch from my setup and was wondering if this would be a working combination or if it will be more or less waste of money? I tried a Marantz 2252b in my room and it did alter the sound towards "fuller" but also...

Hi all, First post here :) so I got myself a 2226B today and I also have a 1060 integrated. I compared the two and find the 1060 to sound better than the 2226B. Now I'm kind of new to all this so forgive me if this is a simple question but how can I use my 1060 as a preamp for my 2226B? And if...

Good afternoon, I have a question regarding harman kardon models 725 and 770 for 100v. In the technical manual I could find, there are two versions only for 120v and for multi-voltage. Question, is there a technical manual for the 100v version of the P725 (HK725) and for the M770 (HK770)? If...

Hi, I saw this vintage amp for sale on my local market and according to what I read, it seems to have a good reputation, but just in case, I want to gather more advice before I pull the trigger. Here is the basic information about this unit, According to the seller, it will come with all the...

Hey All, I am looking to upgrade my phono section with an external Vincent PHO-701. I have been wanting to dive into tubes without upgrading the entire Integrated Amp, so am thinking about adding the Vincent Preamp. My current setup is: MA6300 Integrated Rega P3 TT Ortofon Black 250 LVB Cart...

Well, have set up 2.1 in the past but no sound this time (I know the sub works as I have tried on other systems in my home). I have a parasound new classic 200 preAmp and a Klipsch sw110 subwoofer. I must be doing something wrong with the crossover ideally would like to use the crossover on the...

I use Sony TA-F555ES amp, which I think was once a very good amp, and which I love myself as well. It's time to send it in for some revisions (the wheel to choose between A or B speakers needs to be checked), but there is another issue that I'm not sure I should have the guy look at: the phono...

I have a CT-26V pre-amp that the stand-by power circuit isn't working. Have not had any luck finding a service manual for. Removed the outer cover only to find that nothing has any value markings on it. Any leads would be much appreciated.

A while back, I got an Adcom GFP-555 II preamplifier. On powering it up initially, I found that signals monitored through the unit's headphone jack sounded just fine. The sound coming from the unit's main output was another matter. It had a nasty 60-cycle hum. Has anyone here who has owned this...

Dear All, First of all I want to wish to everyone Happy New Year fulfilled with health and happiness! For the holidays finally I managed to get one set of dreamed: Yamaha C-4 and M-4. The condition of both units is not mint but it is also not bad at all. My whole setup now is: PC -> USB DAC...

Hello good people! I recently installed new diodes, caps transistors, thermistors.. on my Marantz 2270. Now my mistake is that I didn’t recird the output before I started so there’s no way of knowing i mf the problem was present before. I started on the Right channel board first and I checked...

Hello, I recently received a nice marantz 2285B. It is a beautiful and a beast machine, in very good condition. When I plugged it in I noticed a slight HUM coming from the power transformer but it worked perfectly, the relay turned on and the music came. The first thing I did was to recap all...

I'm looking to replace a cheap amp I'm currently using for my setup. From my research, I've narrowed it down to the Denon PMA-600NE and the Yamaha A-S501. Out of these two, it seems the Yamaha would be the better choice. However, I've just recently acquired a Rotel RB-850 for $15 dollars, and it...

I'd like to set up my turntable about 12ft from my receiver on a straight line, but more like 16ft-20ft to have the RCAs wind their way over to the spot where the turntable will sit. So the setup will be turntable to phono preamp, phono pre to receiver. I've heard people say that your turntable...

Hi, helpful fellow AKers have pointed out that the signal from the pre-out on the well-regarded ‘Yamaha a-1 integrated amp’ (note, not the DSP-A1) has to navigate the power section before arriving at the RCA sockets. This routing suggests that the pre-out’s signal quality will be comprised...

I have the opportunity to purchase a Yamaha A1 integrated amp at a low price and am happy to service it myself. I intend to use only it’s pre section teamed up with a my recapped Yamaha P2200. Please could anyone comment on the quality of the A1’s pre amp? I hear that the phono section is very...

Here's my plan that /seems/ like it would work, please tell me if you know otherwise: I have a 5 channel amp* and I plan to use two 100wpc and two 60wpc (leaving one 100w channel unused). I'd like to use the 60w channels with the preamp** main line out (controlled by the volume & other...

Hello all - Does anyone have a suggestion on contacting Dared Audio? Messages through their main website (in Hong Kong?) go unanswered and I’m hoping someone her can direct me to a North American source (distributor, dealer, etc.) so I can get some info. The remote on my SL2000 preamp has...

I have a power amp pre amp combo. I am looking to add a subwoofer to my system with no sub out from the pre. I do have 2 sets of line out however. What is the best way to connect the sub. Also if the sub has only lfe inputs and no high frequency inputs is that a problem? The sub i have been...

Hi All, So I've got a Pat-4 that started to hum recently. I've had it for decades, and this just started happening. A few observations: - The hum is NOT dependent on the pre-amp volume channel, balance treble, hi filter, mono/stereo, or the loudness. - The hum gets worse when turning up the...

Hey guys just bought one of these for a solid deal on ebay with no power cord. Not super familiar with this but will any 9v power supply cord work with this? If not can anyone send any recommendations? Thanks!

I have a NAD 7020 and a pair of JBL 110's that I thought could use more power so tied in a NAD C270 power amp (to the speaker A terminals on the C270). I used the 'variable in' on the C270 as there is an input level adjustment knob on the back and I wanted a little more play in my 7020 volume...

Hey guys working on restoring and upgrading this PL-518 I picked up. Any recommendations for a cartridge I can pick up? Right now my budget for a cartridge is under 100 and I will also need a phono pre amp as well preferably under 100. I had read on some older posts but was pretty confused (I'm...

I just recently just came into a mint SAE A501 and mint Cerwin Vega PR-1 preamp. These power my Polk Audio model 10, series II's. They really came to life, sounds amazing. This is what i should have been running the whole time. The amp to pre amp connection is RCA's. Currently, i am using cheap...
